ISIL staged 'mass executions' in Iraq's Tikrit: rights group

Photograph and satellite imagery indicate that Islamic State in Iraq and the Levant (ISIL) insurgents have carried out mass executions in the northern Iraqi city of Tikrit, Human Rights Watch reported on Friday.
ISIL, radical Islamists who want to re-create a mediaeval-style caliphate straddling Iraq and Syria, has stormed largely unopposed across much of northern Iraq, taking cities including Mosul and Tikrit, seizing border posts with Syria and advancing to within some 100 km (62 miles) of the capital Baghdad.
